how do I create a web report with parms, mysql, struts, and a chart?

oggie

I've just started evaluating brit and it looks like it'll do what I need, but it seems overly complex to get what I want.

I currently have a struts app using hibernate and mysql.

I'd like to be able to have multiple reports in the future, but to start I'd like the 1st one to be a chart of transactions over a period of time. I'd want the report to have inputs as well ( the date range to use for the query).

I've been able to deploy a sample app and see how it works (struts-birt-webreport) , but I'm having a hard time understanding how to build a report with parms.

And how to tie all these things together. I can't seem to find a guide on how that's done. I seem to find bits and pieces and I'm having difficulty putting them all together.

Thanks
